Block after ~4 years without replacing fluid.

[SolarNova]

Greetings all.

 

Since iv just upgraded my GPU i decided to pull apart my 780 classified block to see how bad things were inside after having run it on just distilled and biocide for roughly 4 years.

The loop has never been drained and refilled. The liquid is still clear and clean in the glass rez. The loop uses white soft tubing and monsoon fittings.)

 

Before seeing the pic below, understand that i never experienced any loss in performance from the block. In addition there is absolutely no blockage in the fins or any 'gunk' or other buildup. What your seeing is purely corrosion, and, despite how it looks, its only surface corrosion its not thick or bumpy. This would clean up relatively well.

 

Spoiler

 

Obviously if this were a clear block this would be no good for aesthetics and would have been dealt with as soon as it started to appear , but for opaque blocks this, while not desirable, hasn't affected performance or the clarity of the liquid in the loop.

 

I have not flushed my loop still, i managed to put the new block in without draining (I needed to leak test and check the GPU was fine as it was used, so didn't want to wait). My loop whilst soft tubed is a bloody nightmare to pull apart due to my jury rigged front rad (no native support). So since i need a replaced a piece of tubing anyway as its no longer long enough to have the new GPU block running in the correct flow direction (currently reversed), ill be tearing the whole system down and transferring it in to a new case that fully supports my rads, making it much easier to deal with in the future.

 

 

So yea, i don't recommend not flushing and cleaning your blocks at least once a year, but if u want a hassle free loop, u can just run opaque blocks and tubing, straight distilled and biocide, perhaps some corrosion inhibitor as well, and u should be fine so long as you fully cleaned/prepped the system prior to assembly.

Personally I plan on doing clear anyways since I might use something like an RGB pump, but this is still relatively good info.

Honestly that block looks better then i thought after 4 years or not being touched.

Yeah they have rgb pumps res and blocks.So you could make the coolant look colored like that.

Nice write up, i will do the same for mine after 7 years of not being touched!!!
